**Question 32: What is the difference between speed and velocity?**
The correct answer is: **b. Velocity has direction.**
Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both the speed and the direction of that motion.

**Question 33: An isotope of the element nitrogen has 7 protons and 9 neutrons. What is the name of the isotope?**
To find the name of the isotope, you add the number of protons and neutrons:
7 protons + 9 neutrons = 16.
Therefore, the correct answer is: **a. Nitrogen-16.**
This isotopic notation includes the element (nitrogen) and the total number of nucleons (protons + neutrons).
The correct answer is: **b. Velocity has direction.**
